0–100, higher is better. How it is calculated

Ústav zdravotnických informací a statistiky ČR (ÚZIS ČR) is a Czech government entity responsible for managing the National Health Information System and providing comprehensive healthcare statistics and data analysis. The organization serves healthcare professionals, government bodies, and researchers by collecting, processing, and disseminating healthcare data to improve the quality of healthcare services in the Czech Republic. The website reflects a mature digital presence with a clear focus on data transparency and public service. Technically, the website employs modern web technologies including jQuery, Foundation framework, and slick-carousel for UI components, alongside Matomo for privacy-conscious analytics. The site is mobile-optimized, accessible, and SEO-friendly, with a robust cookie consent mechanism ensuring GDPR compliance. However, some security headers are not explicitly detected, and no public security policy or incident response information is published. From a security perspective, the site enforces HTTPS and uses consent-based analytics tracking, which supports privacy compliance. The absence of WHOIS data limits the ability to fully verify domain registration legitimacy, but the government affiliation and content quality strongly indicate authenticity. No critical vulnerabilities or exposed sensitive data were found in the HTML content. Overall, the website is professional, trustworthy, and well-aligned with its public service mission. Strategic improvements could include publishing explicit security policies, enhancing security headers, and verifying domain registration details to strengthen trust and compliance.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

  1. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

ÚZIS ČR holds a key position as the national authority for healthcare data and statistics in the Czech Republic, operating under the Ministry of Health. Its business model is focused on public service and data management rather than commercial revenue generation. The organization benefits from strong government backing, which supports its authoritative role and access to healthcare data sources. The website links to multiple related government and healthcare registry domains, indicating a broad partnership ecosystem within the healthcare sector. The target audience includes healthcare providers, statisticians, policymakers, and the general public interested in health data. The organization's strategic focus on data transparency, compliance with GDPR, and educational outreach through conferences and publications supports its mission and market position.

Security posture

The website demonstrates a solid security posture with mandatory HTTPS usage and a comprehensive cookie consent mechanism that respects user privacy and GDPR requirements. The use of Matomo analytics with explicit consent and opt-out options further enhances privacy compliance. However, the absence of visible security headers such as Content-Security-Policy and X-Frame-Options suggests room for improvement in defense-in-depth. No incident response or security policy information is publicly available, which could be a gap in transparency and preparedness. The lack of WHOIS data limits domain trust verification, which is a minor concern given the governmental nature of the site. Overall, the security maturity is good but could be enhanced by publishing security policies and implementing additional HTTP security headers.

Recommendations

  1. Implement and publish a comprehensive security policy and incident response plan on the website.
  2. Add and verify HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish a security.txt file to facilitate vulnerability disclosure and improve transparency.
  4. Verify and publicly confirm domain registration details to enhance trustworthiness.
  5. Continue regular audits of third-party libraries and dependencies to mitigate vulnerabilities.

Technical notes

Notes

The website is built using a modern front-end stack including jQuery, Foundation framework, slick-carousel, and magnific-popup for UI interactions. It uses Matomo analytics hosted on a subdomain for privacy-respecting user tracking with a robust cookie consent mechanism. The site is mobile responsive and accessible, with good SEO practices including meta tags and structured navigation. Performance is moderate, likely due to multiple JavaScript libraries and image assets. No CMS is explicitly detected, suggesting a custom or government-managed platform. Hosting provider details are not disclosed. The technical infrastructure supports the organization's mission but could benefit from performance optimization and enhanced security header implementation.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
